Answer:
x² +y² = 16
Step-by-step explanation:
The diagonal of a square is √2 times the side length, so the diameter of a circumscribed circle is √2 times the diameter of an inscribed circle. Each of the two outer circles is √2 times the diameter of the one just inside it, so the outer circle is (√2)(√2) = 2 times the diameter of the inner circle.
The equation of the largest circle with radius 2·2=4 is ...
x² +y² = 16
K x m or km. Product means the result of multiplying.
Answer:
A. How much flour did she use for both cakes?
1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
3 17/20 lb
Step-by-step explanation:
Penny used 2/5lb. Of flour to bake a vanilla cake. She used another 3/4lb. Of flour to bake a chocolate cake
A. How much flour did she use for both cakes?
We solve the above question by adding up the pound of flour used for both cakes.
2/5lb Of flour + 3/4lb Of flour
Lowest common denominator = 20
= 8 + 15/20
= 23/20
= 1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
This is calculated as:
5 lb - 1 3/20 lb
= 3 17/20 lb
Answer:
33.1 grams
Step-by-step explanation:
You know that 58% of the chocolate bar is cocoa and it weighs 57 grams. All you have to do is multiply 0.58 and 57 together. This will give you the amount of grams of cocoa!
58% = 0.58
0.58*57 grams = 33.06
Round up! 33.06 --> 33.1 grams
